BEER-COOLING APPARATUS'.

@PECIFICATION forming part of Letters Patent No. 372,134, dated October 25, 1887.

' Application tiled November 29, 1886. Seri-.11 No. 220,208. (No model.)

To all whom t may concern.'

Be it known that I, CHRISTOPH FRIEDRICH ELZE, ofthe city ofAlsleben-on-the-Saale,in the Province of Saxony, Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Beer-Cooling Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention.

The cooling of the hot wort from iO-70o centigrade to 2-1o centigrade is one of the most essential factors in the preparation of beer. To attain this cooling, various apparatuses are used, which, however, either do not perfectly fulfill the object in view or do so only at great consumption of cooling material-in other Words, at great expense.

In the drawings, Figure l is a View partly in elevation and partly in section. Fig. 2 is a transverse section of the same. Fig. 3 is a plan view,partly in section. modifications and different sectional views of my apparatus in parts thereof. v

The beer-cooling apparatus represented in Figs. l to 7 offers the greatest imaginable utilization of applied cooling material on account of its peculiar construction, in which absolutely all dead-space is avoided, so that its entire surface forms an uninterrupted cooling area. Thus the most complete cooling of the' beer is effected. The apparatus consists of a system of canals, a, triangular in cross-section,arranged in two rows,one above the other, in such manner as to correspond with one another; but the canal system is divided by the cylindrical canal a into two parts,in order to enable one to apply ice-Water and well-Water. Part b is the distributing-channel, from which the beer emerges through the openings c',to be distributed over the cooling-surface of the apparatus. The gathering-'channel d, for the purpose of further cooling the beer, is provided with a triple bottom, and by means of a pipe, e, is connected with the canal system a. The canals are connected with cach other by the semicircular parts f and the intermediate plates, g, so that all formation of corners and angles is avoided and the canals are easily cleansed. The parts f are tightly shutby the front l wall, h, being attached by means of screws. The Whole apparatus is supported Figs. 4 to 7 show by the legs K. The ice-water, which serves for the feeding of the apparatus, enters at the second flooring of the gathering -channel d at y, runs through the same, Aand,loy means of the pipe-connection e, through the canal system, so that after passing the canal c it leaves the same at y. The upper division of the canal system is supplied with well-water, entering through canal c3 at x and emerging from at at x', thus streaming through the canals from below upward. In the upper flooring of the gathering-channel the down-pouring wort is gathered, passing through the exit-opening m, thence to the lower flooring, streaming over the latter in a direction opposite to that of the ice-Water, and through the pipe nis conducted into the cellar. Therefore the gathering-channel is likewise utilized for cooling.

The contrivance represented in Figs. 4 to 6 differs from the preceding only in this respect, l

that th rough increased approximation ofcanals aa longer cooling-surface is created,in order to reach a possibly perfect utilization of cooling material. In this arrangement,as also in the following, the semicircular partf is avoided. The cooling material enters directly from one canal into the other, as shown in Fig. 5 by arrow-marks. Here the gatheringchannel is not provided with double bottoms, the ice- Water going, as will be specified below, directly into the canal system. The latter are, however, closed with the same front Walls, h, and in the same manner. Fig. 4 shows an end view of the apparatus after this arrangement with the front wall, 7i, taken off, illustrating the alternating position of four adjoining canals a, the in and out fiowing of the cooling-water, as also the running off of the Wort external to the canals a. Fig. 5 illustrates a cross-section of the canals after A B. Fig. 6 shows a longitudinal section through the middle of the apparatus as far as one half, the other half being a longitudinal view of the apparatus. The function is here the same as in the contrivance above described. There are also two kinds of cooling-water supplied. The ice-water, however, in this case goes directly into the apparatus at a. without previously passing through the gathering-channel d, and leaves the apparatus at @while at a3 well-Wa- IOO ter enters into the apparatus and emerges at The Wort goes from the distributingchan` nel b over the surface ofthe canals (in the direction of the arrows) to the gathering-channel d, and from here to the cellars.

In Fig. 7, finally, there is illustrated an arrangement of three adjoining canals, forining an oblique direction on account of their being in contact only along the cdges,in order to show that a varying number of canals can be laid near each other, to create a cooling surface corresponding to the work to be done.

Having fully described my invention, what I desire to claim and secure by Letters Pat ent is- In a counter-current beerAcooler in which the downwardllowing wort, passing through asloped cooling area uninterrupted by corners and angles, meets with colder surfaces as itv descends, the combination of the triple-bot tolned gathering-channel d, having connecting-pipe e, conducting-pipe n, and exit-opening m, with a double system of triangular prismatic canals, a, touching each other solely at the angles, divided into ice and Well Water parts by cylindrical canal a', and connected with each other by seinicireular eanaif, having intermediate plates, g, and being tightly shut by Wall h, all substantially as described.
